Neural Processing Unit, Neural Processing System, and Application System

4. The neural processing unit of claim 3, wherein at least one processor is configured to execute computer-readable instructions to cause the internal memory to update the function data by causing the internal memory to delete the function data stored in the internal memory and to causing the internal memory to store new function data received from a memory outside the neural processing unit.

5. The neural processing unit of claim 1, wherein the function data comprises sigmoid, tanh (hyperbolic tangent) or ReLU (Rectified Linear Unit) function data.
